Designed to interact with a 16-bit I/O expander, the firmware was ready for testing.  Though I was still waiting on parts, I wanted to make sure it would all work as expected.  What’s an impatient developer to do?  Create his own SPI slave to replace the missing part, of course! If you’ve gotten anywhere beyond…

I do not enjoy dealing with the vagaries of calendar dates and times… Actually, I pretty much hate it. It’s mostly because I have little patience for arbitrary rules and convoluted systems, and anything as old as the notion of date-times is always filled with historical cruft: half-baked rules, a bunch of incompatible, random-looking, bases…

EvoLink: EVO-All datalink library released

Interacting with vehicles can be pretty tough.  Cars are electrically noisy environments and, being powerful and heavy metal machines, a little tricky (read, dangerous) to play with.  Worse, they’re all different!  Even with the advent of the CAN system and standard, manufacturers can be infuriating in their insistance on doing everything in their own particular…
